Effective May 24, 2021, study space reservations will no longer be needed to enter Mullen Library.
Mullen Library will be open to all who have a current CU ID. In accordance with DC and campus guidelines to protect themselves and those in our community who are unable to receive the vaccine, those who have not been vaccinated should continue to wear a mask at all times.
Library in-person services and schedules will be increasing throughout the summer as we hire and train more student employees. At the beginning of the summer, reservations will still be required to enter Mullen. The Stacks will open for browsing on Monday, May 17. While our circulation staff is still focusing on remote delivery of materials and contactless book pickup, to borrow books from the Stacks you may either use the self-check machine located in the lobby or leave books in bags provided at the circulation desk to be charged out and picked up at a later scheduled time. The current status of all library services can be found in our Libraries COVID-19 Information Guide.
Beginning Monday, April 5, reserving a study space in Mullen Library will be easier, and the library will no longer be closing during the day for cleaning. Frequent disinfecting of all common, high-contact surfaces will be on-going throughout the day. Reservations will be available for all hours that Mullen Library is open. There will be no limitation to how many hours you may reserve, but please be courteous to other students and only schedule for times you realistically expect to use. Library users will be required to submit a reservation request at least 2 hours in advance of their selected time and reservations can be made 10 days in advance.

To be consistent with the quarantine phase for returning students, Mullen Library will be closed for study from January 25 to February 7. Book pickup and other remote services will continue.
The Mullen Library book drop at the rear of the library has been moved to the north rear entrance, closest to the Pryzbyla Center. Books may be returned there 24/7.
Repair of the water main break on the north side of Mullen Library is taking longer than anticipated. At this time, we do not know if we will have any water in the building on Wednesday, January 6, 2021. If you have made a study space reservation for tomorrow or plan to do that, consider this information and re-schedule if you are uncomfortable being in the building without access to water.
Book pickup is not affected.
We are sorry for any inconvenience.
Due to a water main break on the north side of Mullen Library, the library will be without water on Tuesday, January 5, 2021. For this reason, study space reservations are unavailable for that day. Book pickup, however, will still be available.
Repairs are expected to be completed by close of business on January 5.
